This replication archive contains the materials necessary to reproduce the results detailed in the study (main text and appendix). The replication archive contains five main folders, the contents of which are described below:

1. code
2. data
3. figures
4. objects
5. tables

All contents of this replication archive should be maintained within their current directory structure in order to allow for the R scripts to properly access necessary files. 

The R version employed in the creation of this replication archive was R version 4.1.2 (2021-11-01, "Bird Hippie"). The R packages used are 'aod' (1.3.2), 'dplyr' (1.0.7), 'ggplot2' (3.3.5), 'lmtest' (0.9.39), 'sandwich' (3.0.1), 'texreg' (1.37.5), and 'usmap' (0.6.0). Runtimes for the R scripts are noted in the main script 'code/1_main.R'.


(1) The 'code' folder contains 36 R scripts and an additional subfolder ('code/helper') containing functions that are sourced by these R scripts.

The script '1_main.R' sources the other 35 R scripts in the appropriate sequence to produce all results. The scripts are numbered according to the order in which they should be run to undertake replication.


(2) The 'data' folder contains 2 subfolders. The 'data/issue' subfolder contains the issue-specific processed data sets that are used for analysis in the study, along with a variable codebook. The 'data/other' subfolder contains additional data sets on specific policies and home rule status for the U.S. states.


(3) The 'figures' folder contains the figures produced by the replication code and featured in the study (main text and appendix).


(4) The 'objects' folder contains intermediary objects/results of the analyses that are produced by various scripts, stored as Rdata files, and then sourced by subsequent scripts.


(5) The 'tables' folder contains the results presented in the tables in the study (main text and appendix).
